The factors of the expression are (x - 9) (x + 1).
What is an expression?
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the liketerms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
x² - 8x + 9
Determinantformula.
a = 1, b = -8, c = 9
So,
x = -b ± √(b² - 4ac) / 2a
x = 8 ± √(64 - 36) / 2
x = 8 ± √100 / 2
x = 8 ± 10 / 2
x = 4 ± 5
x = 4 + 5 and x = 4 - 5
x = 9 and x = -1
x - 9 = 0 and x + 1 = 0
Now,
The tworoots are (x - 9) and (x + 1).
Thus,
The factors of the expression are (x - 9) (x + 1).

2x-4y=6
solve the equations
Answers
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
x-2y=3
the first equation is
x+3y=3
subsitute
3=3 so therefor
x-2y=x+3y
subtract x from both sides
-2y=3y
add 2y to both sides
0=5y
ofviously y=0 so subsitute
x-2y=3
x-(2)0=3
x-0=3
x=3
x=3
y=0

The error the student made is referring to an angle, m<1, being equal to 80 degrees. It is incorrect to assign a measurement or value to an angle without any given information or reference point.

Answer:
The answer is
Step-by-step explanation:
In order to determine the answer, we have to know that it means "solution".
In any expression where there is a variable, we can replace any value in the variable and we get a result. When we replace a value that it makes the expression equal to zero, that value is called "solution".
So in this case, we have to find a solution for "m":
Finally, the solution is only one and it is 8.
(m - 8)
if m = 8,
Solution for the expression m - 8 = 8 - 8 = 0.
So there is only 1 solution for the expression.
